Application filed November 4, 1912. Serial No. 729,396.

To all whom it may concem:

Be it known that I, MILTON E. SHAVER, a citizen of the United States, residing at 336 Park avenue, Burnham, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hand Brake Mechanism,of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings. which illustrate the preferred form of the invention, tho-ugh it is to be understood that the invention is not limited to the exact details of construction shown .and described, as it is obvious that various modifications thereof will occur to those skilled in the art.

An object of the present invention is to provide a brake mast of that type for use in at cars or in freight cars WlllCh have drop ends or end doors, which are necessary where lading of great length is to be carried or where lading of great weight is to be distributed over two cars.

Another object of the present invention is to provide a telescoping brake mast, the operating portion of which may be dropped into the chain winding portion, and that when so dropped, the top of the hand wheel will be flush with or below the top of the car floor and will not interfere with the lading when'the car is used as above described.

A further object of the present invention is to provide a plurality of brake masts with means common to both of said brake masts through which the brake mechanism may be operated.

A further objectof the present invention is'fiito provide a brake mechanism which may be manually operable either from the end sill of a car or from the track level at the side of the car.

A. still further object of the present invention is to provide a vertical brake mast and a horizontal brake mast and to operatively connect them by a chain with the brake mechanism in such a manner that one of said brake masts will serve'as an anchor for the chain when the other of said brake masts is operated.

Referring now to the drawings in which like reference characters refer to like parts and in which Figure 1 is a plan view of the end portion of a car with the improved hand brake is a sectional View on the line 44 of Fig. 1.

Fig. 5 is a detail view of the chain windlng portion of the vertical brake mast; Fig. 6 1s a plan new of the same; Fig. 7 is a sectional'view on the line 7-7 of Fig. 6 show- 7 ing the supporting member in operative positlon, while Fig. 8 is a similar view showlngt he supporting member in inoperative positlon. Figs. 9 and 10 are detail views of a portion of the vertical brake mast. Fig. 11 is a sectional view on the line 1111 of Fig. 9; Fig. 12 is a similar view on the line 1212 of Fig. 9 and Fig. 13 is a similar View on the line 1313 of Fig. 9. Figs. 14 and 15 are detail views of the bottom portion of the operating part of the vertical brake mast. Fig. 16 is a detail view of a modified form of the chain winding portion of the vertical brake mast; Fig. 17 is a plan view of the same. Fig. 18 is a sectional view on the line 1818 of Fig. 17 showing the suporting member in operative position while ig. 19 is a like view showing the supporting member in inoperative position and Figs. 20, 21 and 22 are sectional views on the lines 20-20, 21-21 and 2222 respectively of Fig. 16.

Referring now in detail to the drawings :.1 represents the draft sills, 2 the end sill and 3 the side sills. These sills are shown of channel form in the drawings, but it will be understood that any otherlsuitable construction may be used.

4 represents the upper or operating part of the brake mast and 5 the operated or chain winding part of the brake mast, while 6 is the vertical brake mastbearing member which is riveted or otherwise suitably secured to the end sill.

The part 4 of the brake mast is made similar to the ordinary brake mast and is provided at the bottom with an enlarged portion 7 of any suitable shape, having an opening therein for the reception of a member hereinafter fully described, and at the top is provided with the ordinary hand wheel 8. The enlarged portion 7 is shown in the drawings as being. square in cross section, but it will be understood that other sections may be used equally as well. I

The part 5 is hollow throughout its length and is provided at the top with a ratchet wheel 9 for engagement with the pawl 10 which may be pivotally mounted on the bearing member 6, and at the bottom is provided with a lug 11, to which the chain 12 is attached, and is also provided with a portion13 on which the chain 12 is wound. The inner surface 14 of the part is made to form an opening'15 of. substantially the same shape as the enlarged portion 7 of the part 4 for the purpose of permitting the part 4 to telescope within the part5. At the top of the part 5, the surface 14 forming the opening'15, is flared outwardly and thus provides a recess within which the lower portion of the brake wheel 8 seats when the vertical brake mast is in inoperative position.

Intermediate the ratchet wheel 9 and the chain winding portion 13, the part 5 is provided at one side with an opemng-l6 which is widest at its central portion. On the side of the part 5 opposite the opening 16, a projection 17 is provided which is hollowed out p on the inside and is provided with an 'openative position.

end 21 of the member 19 is provided with an ofi'set 22 which engages with the portion 23 of the part 5, and prevents the member 19 from moving endwise when it is in-position to support the part 4. This-ofi'set 22 Q is also adapted to engage with the edge 24 Q through the opening in the part of the opening 18 when the member 19 is in a position of rest,'ai d when in such engagement will prevent any tendency to move away from the part 5, 'dueto the shocks which a car. is subject to in general use. The end 21 of the member 19 is also provided with projections or trunnions 25 which, when the member 19 is in a position of rest, contact with the inner walls of the projection 17 on the part 5 on each side of the opening 18 and prevent'the member 19 from being accidentally separated or lost from the part 5.

The bottom portion 7 of thepart 4 is provided with an opening which is of a suit-- able size to permit the member 19 being passed therethrough, the top and bottom of such opening being adapted to engage with said member 19 when the part 4 is in operative position. It will readily be seen that when the member 19 has been asseg finally through the opening 16 in the part of the parts 4 and 5-when the 5 ,'that such parts and 5 are -locked to-- at 35 to form a shoulder or abutment 36 with which the enlarged portion 7 of the part 4 isadapted to engage, such engagement preventing the accidental separation art 4 is in operative position. It will rea y be seen th by providing'the shoulder, or abutment 36, t e opening in the part 7 for the reception of the member 19, as described'in the preferred form may be eliminated. Above the contracted portion 35 the opening 15 in the part 5 is again widened for the reception of the lower portion of the hand .wheel '8 when the part 4 is in inoperative position.

vBesides being provided with a vertical brake mast the car is provided with a horizontal-brake mast 26 one end of which is 'ournaled to the side-sill 3, the other end ein'g journaled in a bracket 27 which may be secured to either the draft sill 1 and the end sill 2 or to both. This brake mast is provided at its outer end with the ordinary hand wheel 28 and is also provided with a ratchet wheel 29 for engagement with the pawl 30 which may be pivotally mounted on the side 3 or on the side ofthe car. The other end of the mast 26 is provided with a slot 31 in which one end of the chain'is secured by a bolt 32 or any other suitable means.

The chain 12 .has one of its ends'secured to the horizontal brake mast 26, and is passed over the sheave 33- which is operatively mounted'in the brake rod aw 34,

the other end of thechain being secured t the part 5 of the'vertical brake mast. will thus be seen thatl when the vertical brake mast is usedto apply the brakes the horizontal brake mast 26 serves as an anchor for the chain'12,' and when the horizontal brake mast is used the vertical brake mast serves as an anchor 'for the chain 12.

When it is not desired to use the vertical brake mast the member 19 may be moved from its supporting position,'as shown in gus Fig. 7 and the parts 4 and 7 telescoped within the part 5. It will be readily seen that when the parts 4 and 7 are telescoped Within the part 5, the top of the brake wheel is flush with the top surface of the car floor, and when in such position is not princinle of zontal brake mast, both of said masts being mounted in one end portion of the car, a hand operating member on each of said shafts, and a common flexible means secured to both of said brake masts through which said brake mechanism is operated.
